This book addresses novel techniques in determining gyroless micro-satellite attitude and attitude rate. The main objective of this proposal is to explore the possibility of using commercially available low cost micro-light star sensor as a stand-alone sensor for micro-satellite attitude as well as attitude rate determination. The objective is achieved by developing accurate and computationally efficient algorithms for the realization of onboard operation of a low fidelity star sensor. All the algorithms developed here are tested with the measurement noise presented in the catalog of the senso...
This book addresses novel techniques in determining gyroless micro-satellite attitude and attitude rate. The main objective of this proposal is to explore the possibility of using commercially available low cost micro-light star sensor as a stand-alone sensor for micro-satellite attitude as well as attitude rate determination. The objective is achieved by developing accurate and computationally efficient algorithms for the realization of onboard operation of a low fidelity star sensor. All the algorithms developed here are tested with the measurement noise presented in the catalog of the sensor array STAR-1000. Proposed methods achieve desired accuracy while estimating satellite attitude and attitude rate using low fidelity star sensor data. Also, they require lower on-board processing requirement and less memory allocation; thus are suitable for micro-satellite applications.
